Re: MTR-2000 continuation
What Bob just said. I have a remote site with a Win10 32 box running just for MTR CPS. Zero success in my experience with 64 bit communicating with the chassis.
Almost positive MTR2K is the same Moto CPS generation where the CPS will run in 64 bit (like MTS/MCS/1st gen Astro) but won't talk to the radio; needs to be 32 bit Windows.

Jeremy,
I worked on a few Tait 800's and got the cable and software from BlueMax49ers.? Fortunately, I did not have to do any re-tuning because I believe that you need extender cards to get to the tuning adjustments.? Is this true?

Hey John,

Read your comparison.?? Good job.?? This is a real comparison.?? And you even came to the same conclusion I did!

" For me the most impressive result of these tests is how well the Yaesu stock antenna performed in varying circumstances."
?
I have found the Yaesu stock antennas also work extremely well.?? As I said before, it's hard to beat the VX-2 antenna, and it works great on the VX-5 as well (which are my go-to ht's)

A real comparison would involve rotating them in an RF chamber and testing radiation patterns.

Re: Antenna for UHF made in Ukraine
We took apart what I recall was a Comprod exposed side mount dipole on 47 MHz and converted it to 6 meters. It was taken out of service because the RG213 coax badly deteriorated after only 10 yrs. It was a base station, not repeater antenna.
?
It had an interesting design. While it was a true folded dipole with both upper and lower loops balance fed at the outside tubing from the tower side, the antenna itself was only maybe 1/8 wave out from the tower leg, meaning that the feedpoint resistance was way below 300 ohms. The manufacturer used RG213 fed inside the upper loop that transitioned to RG63 (.405" OD 125 ohm coax just like the Ukranian) inside the loop aluminum tubing.. If the antenna had been 1/4 wave or more out from the nearest tower leg, the feedpoint resistance might have been say 200 ohms, so a full 1/4 wavelength of RG63 matching section would result in a RG213 feedline resistance of 50 ohms.? What was done was to make the 1/4 wavelength of RG63, under an electrical 1/4 wavelength to the feedpoint opening in the loops where the shield was grounded to the end of the upper loop tubing (as in the Ukrainian antenna), and then instead of the center conductor of the RG63 directly connecting to the end opening of the lower loop tubing, about 7 inches of open RG63 with it's shield connected to the lower tubing end, with the RG63 open section extending further down inside the lower loop tubing, and just center conductor, no coax shield across the feed point air gap, thus apparently capacitively loading the matching stub to make it a 1/4 wavelength electrically, but apparently impedance? tapping down between the transition to RG213 end and the open end of RG63 inside the lower loop load.?
?
The result was a narrower SWR bandwidth (say 3 /MHz instead of 5 MHz with the competing Sinclair side mount exposed folded dipole out 1/4 wavelength from the tower). Also more RF current in the tower, so less back side pattern loss? than with the Sinclair. With the Comprod, the feed point termination measures an open instead of short from center conductor to shield.?
?
Possibly the Ukranian exposed dipole may also start with RG213 pigtail and transition inside the element tubing to a 1/4 wavelength RG63 matching section like would be with the Sinclair antenna.

Too bad that the Ukrainian dipole arrays are no good for repeater use :(
If they would sell the dipoles alone maybe someone else could make proper phasing harnesses for them using RG-214.

It's not so bad to do RF field measurements outdoors.
?
The EMI test site at Bell Labs in Holmdel NJ was essentially an outdoor site ground plane in an open field (with a fiberglass structure over it) and then a vault below ground for the test equipment and personnel.? The Holmdel location was supposedly selected (in the 1920s) because it was in a bit of radio hole relative to street car electrical noise from NYC, or so the legend went.
?
We also had RF anechoic chambers for pre-testing, but the data for the FCC filing was collected from the outdoor open field site.
?
FYI, I recently tested my SDRplay RSP1A SDR receiver connected to my HP8647A sig gen and found that the SDRPlay signal strength indicator (reading in dBm) was within 2dB what the HP said it was producing, from -30 dBm to -110 dBm.? I only tested it at 146 MHz, but I should retest it at 30, 50, 446 and 915 and see if matches there was well.
?
The SDRplay connected to a reasonable sense antenna might make for a convenient way to A-B two test antennas.? It wouldn't produce an absolute measurement, but it should show if antenna A is better than antenna B, and by how many dB.
?
KX4O's write up on antenna comparisons is excellent!

Thanks John for the page and actually acknowledging return lost is a factor. I found most "hams" don't know or care about that scale for measurement especially, on "eham".
Curious, what is your construction type of the RF chamber? I do it the cheap (and not so accurate) way with use free air (outside the shop).

For a GMRS repeater, transmit would be the 462 freq, and receive would be the 467 freq.

Re: Tuning/programming a Kenwood NXR 1800 repeater
Except that the TKR-720/820 and 750/850 need the front end helicals tuned if you're moving it more than a few hundred KHz.

If you are, you'll need to purchase the right version of the repeater as Kenwood makes specific versions for specific band ranges. ? I have cut and past right from the Kenwood commercial site, which you can find by doing a google search on Kenwood NXR 1800.? ? As far as programming, you'll need the program cable and software to make it work and to setup the repeater.??? If you have never done this before it will be a learning curve as it's just not a few clicks and save it back to the radio.??? Kenwood repeaters, if you select the right band range, do not need to be tuned on a service monitor as the software writes the frequency back to the repeater and adjust the receiver and transmitter to the right frequency.??? However, I always like to check it on the monitor just to make sure everything is setup right as far as frequency, deviation and power out settings as a few basic checks.
